Distance Shooting

Broad Question

How much does the distance away from the basket affect the chance of making the shot?

Specific Question

How much does shooting a shot from 6, 10, 15, or 20 feet affect the chance of making the shot?

Variables

Independent Variable: Distance from Hoop

Dependent Variable: Number of Shots Made


Variables to be Controlled:

Same person shooting

Same basketball used

Same basketball hoop being used

Hypothesis

I hypothesize that I will make the best percentage of shots from 6 feet away from the basket, followed by 10, 15, and then 20 feet.

General Plan



Experimental Design

I am going to conduct an experiment that will help me determine how much being farther away from the basket affects the chance of me making the shot. The experiment will be conducted at my house. There will be three people involved in the experiment. I will be shooting. One person will be rebounding and recording how many shots I make and another person will be documenting the experiment with a camera. Four different distances from the hoop will be tested. Each distance will be tested twenty times. This means that I will have to shoot a total of eighty shots. All the data will be recorded on a printed out copy of a spreadsheet, which will then be transferred onto the computer when I’m at school. The experiment will be documented with a digital camera and uploaded onto the computer, then saved on a thumb-drive that I will bring to school and then save them on my x-drive. Then I will be able to upload them to my Wiki, as well as make prints for my display board.

Materials List

  1. Clipboard
  2. Pencil
  3. Copy of Spreadsheet
  4. Basketball
  5. Digital Camera
  6. Two other people (Rebounder/Recorder and Photographer)
  7. Basketball Hoop

Detailed Procedure

  1. Go to my house with all materials.
  2. Stand six feet away from hoop.
  3. Shoot the ball.
  4. Record the results on spreadsheet.
  5. Repeat steps 2-4 nineteen more times.
  6. Stand ten feet away from hoop.
  7. Repeat steps 3,4 and 6 nineteen more times.
  8. Stand fifteen feet away from hoop.
  9. Repeat steps 3,4, and 8 nineteen more times.
  10. Go to twenty feet away from hoop.
  11. Repeat steps 3,4, and 10 nineteen more times.


Background Research

  1. good arc gives the shot more chance of going in
  2. backspin on the ball helps it go in if it hits the rim
  3. A warm basketball is bouncier than a cold basketball because warm molecules move faster than cold molecules.
  4. when you jump as soon as you stop going up you start going down and it’s better release at the top of your jump on a jumpshot

Data Analysis


Conclusion

The purpose of this experiment was to find which distance would be the best to shoot from. The results of the experiment were that I made ninety percent of my shots from six feet away from the hoop. I made sixty-five percent of my shots from ten feet. I made Fifty-five percent of my shots from fifteen feet and thirty-five percent from twenty feet.

Discussion

My hypothesis was that I would make the best percentage of basketball shots from six feet, followed by ten, fifteen, and twenty feet. My results support my hypothesis. There is a relationship between the independent and dependent variables. Some patterns of my experiment are that the farther away from the basket I got the more my accuracy decreased. I think the tests I did went smoothly because I didn’t have any problems with the test. If I could improve my experiment I would take some shots from different angles. An interesting future study might be whether it’s easier to bank a shot or not.
